Thank you for the helpful reading. sorry i did not to go into more detail about the build i would like to do. I would like to make 400 rwhp. but i would also like to retain a turbo with a good responce. im looking at some faily cheap manifolds i looked at using the stock one but thats just not the way to go. I plan to upgrade to top feed injectors with fuel pump ect but i am still reaserching my fuel system. not sure exactly wat i am going to do yet. As far as engine managment goes im realy hoping to be able to afford the haltech. I am oredering things slowly and making sure i buy the right stuff as time realy isnt a factor. considering i have no licence(drifting in parking lot bad idea). Any tips usfull thanks brian

hello my name is brian and i am new to the forum. I have a 1990 gts-t type m with rb25det. Currently i am without a drivers licence for the next 6 months. i will be doing some modification and would like some advice. currently on the car i have a greddy downpipe with an apexi cat back for my exaust. i also have an old blits sbc witch will only allow me to boost to 12 psi. the parts that i have but are not on the car yet are brembo brake roters an hks bov and an intake manifold. the next things on the list to order are a greddy oil cooler/relocation kit along with a trust fmic. what i am wondering is witch turbo i should go with? i would not like to retain my factory manifold and i would like a turbo that can run at least 2 bar safley with a decent responce. any suggestions i was looking at a used hks gt2540 but its gone now. dont want to spend an arm and a leg on a turbo. ill wate untell i get it and spend some doh on a nice stand alone ecu. any suggestions on the turbo or general good ideas whan adding boost are appreshiated thanks brian!
